Brazes (bonds) together components to assemble metal parts as specified by layout, work order or blueprints, using hand torch: aligns and clamps work pieces together, using rule, square or template or sets up and places them in fixtures, jigs or vise.
Assembles, mounts and adjusts compressors, condensers, oil separators, expansion tanks and other components in specified location per blueprints, piping diagrams, schematics, technical manuals and other specifications. Selects torch tip, flux and brazing alloy from data charts or work order.
Connects hoses from torch to regulator valves and cylinders of oxygen and specified fuel gas, acetylene or natural. Turns valves to start flow of gases, lights flame and adjusts pressure and mixture of gases to obtain desired color and size of flame.
Brushes flux onto joint of work pieces or dips braze rod into flux to prevent oxidation of metal. Guides torch and rod along joint or seam of work pieces to heat to brazing temperature and melt braze alloy to bond work pieces together. Examines seam and rebrazes defective joints.
Cleans joints of work pieces, using wire brush or by cleaning solution.
Examines product for defects, utilizing knowledge of manufacturing and quality standards, to ensure conformance to product specifications.
